Equipped with top-tier technology, special effects makeup artist Tang Li crosses over into the used car market, exposing the false disguise of accident-involved cars with a unique "makeup removal" technique. Facing constant obstruction from car dealer Jin Dayal and behind-the-scenes repair expert Lao Gui, she and her assistant Su Che use special effects developing powder and chemical reagents time and again to pierce the lies of spliced cars and flood-damaged cars. As the black-hearted car dealer sets a more covert mechanical trap, the greatest suspense remains whether Tang Li can use the makeup case in her hand to completely clear up the industry chaos and establish transparent new rules for the used car market.
